A review is given of the current state-of-the-art of experimental studies and the theoretical
understanding of nonlinear phenomena that occur in the ionospheric F-layer irradiated by …

Steady state spectral features of stimulated electromagnetic emissions (SEEs) for their major
emission components (DM, NC, BC, BUM, and BUS) are studied in a wide pump wave …

Results of systematic study of Stimulated Electromagnetic Emission (SEE) steady state
spectrum dependence on the pump wave frequency f0 are presented. Investigations of the …

We present a short review of research using “Sura,” a multipurpose radio facility of the
